| Ranges | Pt100 RTDs: -32 to 1112°F (-200 to 600°C), Alpha: 0.00385 Cu10 RTDs: -328 to 500°F (-200 to 260°C) |
| RTD Excitation | Pt100: 0.45 mA, maximum Cu10: 5.0 mA, maximum |
| Lead Wire | Resistance: 40% of the base sensor resistance maximum or 100 Ω (whichever is less) Effect: Changing from 0 Ω lead resistance (each lead) to maximum allowed lead resistance: Error <1% of largest span PT and Cu ranges; -32 to 1112°F (-200 to 600°C) for Pt and -328 to 500°F (-200 to 260°C) for Cu |
| Pushbutton Adjustment | Effective zero offset: >95% (Inputs >10 mV): Effective span turn down: >95% |
| Local Range Selection | By DIP switch |
| Response Time | Dynamic deadband: Relay status will change when proper setpoint/process condition exists for 100 ms Normal mode: <250 ms (analog filtering) |
| Setpoint Effectivity | Setpoints are adjustable (by pushbutton) over 100% of the selected input span |
| Repeatability | ±0.05% of FS, ±1°C (constant temp) |

| Material | Gold flash over silver alloy |
| Electrical Life | 105 operations at rated load |
| Stability | ±100 ppm of full scale/°C (±0.01%/°C) |
| Common Mode Rejection | 120 dB at DC, >90 dB at 60 Hz, or better |
| Isolation | >1800 V DC or peak AC between input, output and power |
| ESD Susceptibility | Capable of meeting IEC 801-2 level 3 (8 kV) |
| Humidity (non-condensing) | Operating: 15 to 95% RH at 113°F (45°C) Soak: 90% RH for 24 hours at 140°F (60°C) |
| Temperature | Operating: 32 to 140°F (0 to 60°C) Storage: -13 to 185°F (-25 to 85°C) |
| Host Module Interface | IR link, same specs as phase 1 modules |
| Agency Approvals (EMC and Safety) | UL recognized per standard UL508 (File No.E99775) CE conformance per EMC directive 2004/108/EC and low voltage directive 2006/95/EC (Input <75 V DC, only) RoHS compliant |
| Power | 9 to 30 V DC, 1 W typical, 2 W maximum |
| Dimensions | 4.39 x 3.54 x 0.69" (111.6 x 90 x 17.5 mm) DIN rail case |
