Monitoring Modes
Monitors SSR Output and Input for shorted SSR output, loss of line voltage, loss of load, short external to SSR, and loss of DC power.
Power/Status Indication
Green LED energized when power is applied and normal operating conditions are present, i.e. status is OK.
Power Supply
10-14 VDC (12VDC) or 20 - 30 VDC (24VDC), less than 1.5 Watts power consumption.
Input Mode
Interrupted; input to SSR and SSRMON is forced off for ~ 150 - 200mS every 10 seconds to test SSR and SSRMON is based on drive signal.
Control Input Impedance
~4K ohms
Control Voltage
Continuous: 5-32 VDC
Alarm Output
Single Relay Contact 200 VDC/0.5A max. Contacts open upon fault or loss of board power. Contacts are closed when no faults are present.
Alarm Response Time
Typically less then 50 mS from the last control input cycle. Up to 10 seconds on interrupted input version with control input on 100%.
AC Line Voltage
100-660 VAC 50/60 Hz.
Input/Output Isolation
400 Vrms (25 C for 1 second).
Off State Leakage Current
6 mA rms max across SSR output.
Off State Blocking Voltage
1200 Vpk (max 1 minute duration).
Operating Temp. Range
0 to 60 C.
