Description
The FO-RCT/FO-RCR Satellite Relay Receiver module and the desktop Relay Control Transmitter form a Fiber-Optic Integrated Relay Link for remote control of Potential-Free Contacts (PFC).
The Receiver (FO-RCR-1-30A) with one 30-Amp SPST latching relay or the Receiver (FO-RCR-4-5A) with four independent 5-Amp SPST latching relays is used for remote ON/OFF power control or for switching up to four functions as required by equipment under test (EUT). The Relay Controller has a logic level range of up to ±20 VDC or simple shunted input up to 4 channels. Alternately, four front-panel toggle switches provide control.
The Receiver filtering and shielding provide good immunity from electromagnetic interference (EMI), electromagnetic pulse (EMP) or high voltages associated with plasma research. This allows for uncompromising electromagnetic compatibility (EMC) for engineering and testing. The satellite relay module is validated for RFI/EMI validated for EMC at 200 V/m (46 dB V/m) at 500 kHz to 18 GHz and 600 V/m (pulsed 5% duty-cycle &5μs rise-time) 1 GHz to 2.5 GHz.
Three integral 'AA' batteries provide power to the satellite module for up to 8-days. Other relay contacts and configurations are available at special request i.e. SPST 60-Amp, DPDT or signal relays.
