Posessing many high-level standard features, additional function setup items also appear in the control menu when a function is selected, simplifying the selection process. Units feature a universal input for thermocouple Types J, K, E, T, L, N, B, C, S and R, RTD’s, a differential input (-10 to 10 mVdc), and a process input (0 to 20 mAdc, 0 to 10 Vdc). A standard 24 V isolated, regulated power supply is included; operates most standard 4 to 20 mA transmitters. Standard features include autoune, fuzzy logic, fully adjustable PID, auto/manual control with smooth transfer and front panel activation key, percent output indicator, peak and valley indicator, loop break protection and indication. For process inputs, the display is fully programmable from -1999 to 9999 with selectable decimal point location. Most thermocouple and **CN72033.** RTD inputs show whole or tenth degree displays. The CN72000 Series can be programmed for on/ off, PID, heat/cool, or latching alarm. All outputs are isolated from the inputs. Outputs include 10 A relay, and scalable 0 to 20 mAdc. ## **Specifications** **Selectable Inputs:** Thermocouple, RTD, DC voltage or DC current **Input Impedance:** **Thermocouple:** 3 MΩ minimum **Voltage:** 5000 **Current:** 10 **RTD Current:** 200 µA maximum **Display:** Two 4-digit, 7-segment, 6.35 mm H (0.25") LEDs **Accuracy:** ±0.25% of span, ±1 least significant digit **Supply Voltage:** 100 to 240 Vac, nominal, 10 to 15%, 50 to 400 Hz **Single Phase:** 132 to 240 Vdc, nominal, 10 to 20% **Operating Temperature:** -10 to 55°C (14 to 131°F) **Control Output Ratings** : **Relay:** SPDT, 10 A @ 240 Vac **Resistive:**[1] ⁄2 hp @ 120 Vac, 1 ⁄3 hp @ 240 Vac **Alarm Relay:** SPST, 3 A @ 240 Vac resistive **Proportional Current (Isolated):** 0 to 20 mAdc, scalable into 600 Ω maximum **SSR:** 2.5 A @ 240 Vac @ 25°C (77°F); derates to 1.25 A @ 55°C (130°F) **DC Pulse (Isolated):** 15 Vdc @ 20 mA **Weight:** 369 g (13 oz) **P-69** **P** ## **Inputs** **==> picture [514 x 346] intentionally omitted <==** **----- Start of picture text -----**
