Command and control devices

The three-phase monitoring relay DUW-32 monitors the

three-phase mains for the correct phase sequence as

well as for failure of a phase.

The device is supplied by the measuring circuit L1 – L2

– L3 – (N). The output relay is pulled up in normal

operation. The output relay drops out if the phase

sequence is violated, a phase fails or the voltage drops

below 75% of the rated voltage. The error is displayed

by the red LED. In order to bypass brief mains faults,

the off time t2 can be delayed by 0.1 to 10 seconds with

the potentiometer

Pluggable replacement module for surge arrester BSA-GPJ-20

MOV: high-performance varistor and gas-filled spark gap

The devices of the BSA-GPJ series were developed to protect sensitive devices and electronics in connection with upstream class I+II devices.

The BSA-GPJ-20 (2+0) includes metal oxide varistors and gas-filled spark gap for protection in the TN-S network. In the event of a defect, the two-part device enables a simple and quick replacement without new wiring, by pulling out the plug-in module and inserting a new module. The devices have a mechanical status display and a remote signaling contact.

MOV surge arrester: High-performance varistor 

The devices of the BSA-W1L series were developed to protect against direct and indirect lightning discharges. They offer protection in the zone transition 0A - 1 according to IEC 62305.

The BSA-W1L (4+0) consist of four gas-filled spark gaps in series with high-performance metal oxide varistors. They are free of leakage current and can therefore be used in the pre-counter area. In the event of a defect, the two-part device enables a simple and quick replacement without new wiring, by pulling out

the plug-in module and inserting a new module. The devices have a mechanical status indicator and a remote signaling contact.

Replacement module for surge arrester BSA-W2-20

The devices of the BSA-W2 series were developed to protect against the effects of indirect lightning discharge and induction voltage. They offer protection in zone transitions 1-2 according to IEC 62305. The BSA-W2 (4+0) contains four high-performance metal oxide varistors to protect three-phase TN-S networks with separate

N and PE conductors. In the event of a defect, the two-part device enables a simple and quick replacement without new wiring, by pulling out the plug-in module and inserting a new module. The devices have a mechanical status indicator and a remote signaling contact.

Connection bridge for looping through the plus and minus pole of the 17.5mm supply voltage.

With the limit switch RG 3300, Relmatic expands the product range of modules for interface technology with the highest functionality and reliability.

The current monitor RG 3300 is used for limit value monitoring of 0 ... 1/5 A DC and AC currents. The high level of reliability and safe isolation are essential features that guarantee trouble-free system operation.

Two switching output channels can be configured independently of each other. The switching point and the switching hysteresis can each be set with a 12-turn potentiometer on the front of the device. The switching status is displayed with a yellow LED on the front of the device. 

The current monitoring relay SIW-25 serves for monitoring the current level in 1-phase AC circuits. It is suitable for:

- remote equipment diagnostics (short-circuit, increased

peak current)

- Priority switching (2 devices may not be active

simultaneously - protection against overload)

- Current flow display (informs which devices are

switched on)

- Switchover of devices

On exceeding the set current level, the relay switches

on after the set delay. The hysteresis comes into effect

when resetting to the normal state.

The advantage of the SIW-25 is that the cable is fed

through underneath the distributor cover.

Relmatic's SIW-1 series current monitoring relays monitor AC currents in 5 ranges from 0.1 - 1A, 0.2 - 2A, 0.5 - 5A, 0.8 - 8A and 1.6 - 16.0 A (high range) and are used to monitor all 1-phase AC low-voltage circuits for use.

The monitoring of the maximum current can be set from 10% to 100% of the end value. To suppress brief peaks, the delay time can be set from 0 - 10 seconds.

The EPU-41 monitoring relay monitors the voltage level in the 1-phase network for overvoltage and undervoltage, as well as for phase failure. The monitored voltage is also the

power supply for the device. In normal operation, the output relay is picked up. In the event of overvoltage or undervoltage, or if the phase fails, the output relay drops out. The over- or undervoltage is indicated by the red LED. In order to temporarily bridge brief disturbances on the network, the switch-off time t can be delayed from 0 to 10 seconds using the potentiometer.

The EPU-42 monitoring relay monitors the voltage level in the 1-phase network for overvoltage and undervoltage. The monitored voltage is also the power supply for the device. In normal operation, the output relays are switched off. In the event of overvoltage, relay 1 switches on, and in the event of undervoltage, relay 2 switches on. The red and green LED displays clearly indicate the error status. In order to temporarily bridge brief disturbances on the network, the response time t can be delayed from 0 to 10 seconds with the potentiometer.

The installation relay ISR1-316 contains 3 changeover

contacts for a 16 A / 250 V AC load.

The narrow, 17.5-mm DIN housing saves space in the

switching cabinet and has a high switching capacity.

It can be operated with a supply voltage of 230 V AC

or 24 V AC/DC and has a built-in protection diode and

interference suppression capacitor.
