Features
| Inputs | Thermocouples supported: B, E, J, K, R, S, T Overvoltage: ±10 V differential Common mode: 1800 V DC (input to ground) Limit differential (deadband): 0.2% to 100% of span. Set by pushbutton adjustment Ranges: B: 167 to 3308°F (75 to 1820°C) E: -445 to 1832°F (-265 to 1000°C) J: -346 to 1400°F (-210 to 760°C) K: -445 to 2502°F (-265 to 1372°C) R: -13 to 3200°F (-25 to 1760°C) S: -13 to 3200°F (-25 to 1760°C) T: -445 to 734°F (-265 to 390°C) |
| 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, ±33.8°F (±1°C) (constant temperature) |
| Relay Contacts | 2 SPDT (2 form C) Relays, 1 relay per setpoint Current rating (general use): 120 V AC: 5 A; 240 V AC: 2 A; 28 V DC: 5 A Material: Gold flash over silver alloy Electrical life: 105 operations |
| Local Range Selection | By DIP switch |
| Stability | ±100 ppm of FS/°C |
| Common Mode Rejection | 120 dB at DC, >90 dB at 60 Hz, or better |
| Isolation | 1800 V DC or peak AC between, contacts, input and power |
| ESD Susceptibility | Capable of meeting IEC 801-2 level 3 (8 kV) |
| Host Module Interface | IR link |
| Wire Terminations | Screw terminations for 12 to 22 AWG |
| Humidity (non-condensing) | Operating: 15 to 95% RH at 113°F (45°C) Storage: 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) |
| 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; 1.2 W typical, (3.25 W maximum both relays energized) |
| Dimensions | 4.39 x 3.54 x 0.69" (111.6 x 90 x 17.5 mm) DIN rail case |
