Sensitive Signal Indication (SSI) Relays

Phoenix Contact Sensitive Signal Indication (SSI) Relays are part of the PLC-INTERFACE relay family that houses an internal amplifier circuit and an auxiliary supply. This ensures reliable switching coil actuation even with weak input signals. The SSI relays can be used for 5V, 12V, and 24V DC input signals with less than 1mA control current. The narrow 6.2mm design of these relays allows for space-saving on the DIN rail and the relays are available in screw or push-in connection technology.
