Relay Specifications Set all Variable Alert Statuses to logic 0 Type Single pole, double throw (SPDT) Set Bypass and Inhibit Statuses to logic 1 Minimum Switched Current Electrical Maximum Contact Voltage 100 mA @ 12 Vdc Modbus Note: Monitor Alarm Inhibit switch, Activate Inhibit and Monitor Trip Multiply switch Maximum Switched Power 50 k or less (shorted) mapped in the Modbus Gateway will remotely inhibit Alert and Danger statuses or activate Trip Multiply respectfully. 300 Vrms 150 Vdc 160 W dc 1500 VA ac 500 k or greater (open) De-activate Inhibit Contact Life Sealing Epoxy Insulation Resistance Reset all latched Alert statuses 100,000 cycles @ 5 A, 250 Vac Use the Reset input to reset all latched alarms and latched relays. If the condition driving the status no longer exists, short-
circuiting the RESET contact to RESET RTN will: 200,000 cycles @ 1 A, 24 Vdc Reset 1000 M minimum @ 500 Vdc Reset all latched Danger statuses Electrical
Inhibit, Reset, and Trip Multiply Inputs
Activate Reset Reset all latched Not OK statuses Inhibit/Trip Multiply 50 k or less (shorted) Reset all latched relays When configured for Inhibit the Inhibit input will inhibit (bypass or inactivate) Alert and Danger statuses. Short circuiting the INHIBIT contact to INHIBIT RTN will: 500 k or greater (open) De-activate Reset Modbus Note: Writing a non-zero value to the Modbus register Reset Latched Statuses mapped in the Modbus Gateway will reset the monitor remotely. Users can use software to configure the Inhibit/Trip Multiply input as either Inhibit or Trip Multiply. When configured for Trip Multiply short-circuiting the Inhibit/Trip Multiply contact to RTN will increase Alert and Danger set points.
All outputs are short-circuit protected. Set all Variable Danger Statuses to logic 0
