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. |
