Edwards SIGA-CRH — addressable Signature Series control relay module for interfaces needing a high voltage, high current relay.
Ordinary Signature control relays are pilot-duty parts; this one switches the load itself, so door closers, fans and dampers run straight off the loop. It carries one relay with two identical Form C contact sets that transfer together, and the output terminals are not supervised.
- 7 A at 120 V and at 240 V 50/60 Hz (PF 0.75); 3.0 A at 120 V and 1.5 A at 240 V (PF 0.35); 6 A resistive at 24 VDC; audio switching 0 to 20 kHz
- SLC 15.20 to 19.95 VDC, 75 µA maximum standby and activated; one electronically assigned address
- Personality Code 8, dry contact output; up to 60 per signaling line circuit
- Double-gang or 4 in. square box, 2-1/8 in. deep; UL 864 and CAN/ULC-S527; EST3, EST3X and iO Series
The plain SIGA-CR shares Personality Code 8 and the same 75 µA draw but is rated only 2 A at 24 VDC pilot duty and 0.5 A at 120 VAC. SIGA-MCR is that relay on a UIO motherboard and SIGA-CRR reverses polarity.
