Alarm Contact Rating
Four relays (SPST) each rated at 3 A (resistive), 240 V ac maximum. The contacts are
unpowered.
Use either high voltage (greater than 30 V RMS and 42.2 V PEAK or 60 V dc) or low voltage
(less than 30 V RMS and 42.2 V PEAK or 60 V dc). Do not use a combination of high and low
voltage.
Alarm Connection
Connection made by four removable two-position terminals through one of four
½-inch conduit holes in the case. Wire size: 12–18 AWG.
Analog Output
Two isolated outputs, 0/4–20 mA. Maximum impedance 800 ohm.
Recorder Output Connections
Connection made to a terminal block through one of four ½-inch conduit holes in the case.
