1-5 mA @ 200?? nominal input impedance 4-20 mA @ 50?? nominal input impedance 10-50 mA @ 20?? nominal input impedance Selectable Current (SC) comes with three load resistors for selecting1-5, 4-20, or 10-50 mA
0.25-1.25 V @ 1M??, minimum 1-5 V @ 1M??, minimum Consult factory for dual input and special range options.
Output: Factory-configured with one (Single DCA) or two (Dual DCA) single pole/double throw (SPDT), form C, mechanical relays rated for 5 A @ 117 Vac non-inductive, or 28 Vdc. User selects Normally Open (NO), Normally Closed (NC), or any combination of NO/NC configurations during installation. Fail-safe/Non-fail-safe configuration factory-set. Double pole/double throw (DPDT), form 2C and 7.5 A relays available as options.
Power: 24 or 45 Vdc ??10%, 5 watts nominal 100, 117, 200, 220, or 240 Vac ??10%, 50/60 Hz AC power inputs not available with PC-style housing
Trip point settings repeat within ??0.1% of span. Dead Band: 1% of span, standard. Alarm Response: 50 milliseconds for step change of 1% of span. Line Voltage Effect: ??0.005% per 1% line voltage change (ac or dc). Isolation: No galvanic path between input, output, and power. Accuracy: Front panel potentiometers capable of setting trip points from 0 to 100% of span. Effect of Ambient Temperature on Performance: Less than +/-0.018% per degrees C through the specified range (Less than ??0.01% per ??F)
