| Specifications continued Accuracy: ±0.25% of span ±1 count. Resolution: 1° or 0.1°, selectable. Line voltage stability: ±0.05% over supply voltage range. Temperature stability: 4 ,uV/°C (2.3 ,uW°F) typical, 8 ^V/°C (4.5 ,uW°F) max. (100 ppm/°C typical, 200 ppm/°C max.). Isolation: Relay and SSR outputs are isolated. Pulsed voltage output must not share a common ground with the input. Supply voltage: 100 to 240 VAC nom., +10/-15%, 50 to 400 Hz, single phase; 132 to 240 VDC, nom., +10/-20%. 5 VA maximum. Note: Do not confuse controller power with heater power. The controller does not supply power to the heater, but only acts as a switch. For example, the controller could be powered by 115 VAC, but controlling 12 VDC to the heater. Operating temperature range: -10 to 55°C (1 4 to 131°F). Memory backup: Non-volatile memory (no batteries required). Control output ratings: AC SSR (SPST): 3.5 A @ 250 VAC @ 25°C (77°F); derates to 1.25 A @ 55°C (130°F). An SSR is recommended for longer life than a mechanical relay. Mechanical relay, SPST Form A (Normally Open): 3 A resistive, 1.5 A inductive @ 250 VAC; pilot duty: 250 VAC; 2 A @ 125 VAC or 1 A @ 250 VAC. Switched voltage (non-isolated): 5 VDC @ 25 mA. Alarm relay, SPST Form A (Normally Open): 3 A resistive, 1.5 A inductive @ 250 VAC; pilot duty: 250 VAC; 2 A @ 125 VAC or 1 A @ 250 VAC. Weight: 227g (8 oz.). Agency approvals: UL & CSA. Front panel rating: Type 4X (IP66). |
