SLD/FIXED .25A W/O RELAY Datasheet The Current Switch Device (CSD) Series of digital output current switches are non-intrusive devices designed to detect current flowing through a cable or wire. A cost effective solution for monitoring on and off status or proof of operation, these units are ideal for monitoring very small current loads on motors driving fans and blowers, pumps, heating coils, and lighting. The CSD models with command relays not only monitor the current flowing through the cable but also facilitate the start and stopping of the motor. These units also provide a universal solid-state output and do not require a power supply. Completely self powered, these units draw their power from current induced from the cable or line being monitored. CSD Series Current Devices are available in the following types: solid core, setpoint fixed solid core, setpoint adjustable solid core with command relay, setpoint adjustable split core, setpoint fixed split core, setpoint adjustable split core with command relay, setpoint fixed split core with command relay, setpoint adjustable 12 VAC/VDC and 24 VAC/VDC accessory command relays Features dual function — monitors current and motor start and stop 100% solid-state output — has no moving parts to fail polarity insensitive output — provides easier wiring snap-in mounting bracket — simplifies installation small size — fits in tight enclosures
