The CN245 Series provides dual LED displays for local indication of process value and setpoint value. Control methods include on/off, PID, auto-tune and manual-tune. Controller includes a 3 setpoint ramp/soak control feature, alarm functions, RS485 communications and heater loop break alarm. Beside operation as multi-setpoint PID controller, the unit can be ideally used as signal converter thanks to a universal input (selectable by parameter for up to 18 different signals) and the analog output which is galvanically ## isolated and programmable for rescalable retransmission of process/setpoint value. An optional software package CN-SW-HW-KIT includes cable and configuration module for quick configuration of units, as well as copying configuration parameters from one unit to another. The configuration module can also be purchased separately and with a built-in battery feature, configuration settings can be downloaded and copied to module without power applied to controller. Module can then be plugged into a new unit without power applied and the configuration setting can be transferred for easy set up for multiple units. ## **Specifications** **Supply Voltage:** 24 to 230 Vac/Vdc ±15%, 50/60 Hz **Power Consumption:** 3 W **Display:** Two 4-digit, 10 mm (0.4") green (SV), 7.6 mm (0.3") red (PV) **Accuracy:** ±0.5°C temperature, 0.2% reading **Resolution:** 1°/0.1° 10 µV process **A/D Conversion:** Sigma-delta **Reading Rate:** Programmable **Digital Filter:** Programmable **Operating Conditions:** Temperature 0 to 45°C (32 to 113°F), humidity 35 to 95 RH% **Enclosure:** Polycarbonate V0 **Front Panel:** Silicon V0 **P-1** **Dimensions:** 90 H x 72 W x 64 mm D (3.5 x 2.8 x 2.5") **Weight:** 195 g (6.88 oz) **Inputs: Thermocouple:** K, J, S, R **RTD:** Pt100, Pt500, Pt1000, Ni100 **Thermistor:** PTC 1K, NTC 10K (B 3435K), NTC 2252Ω **Process:** 4 to 20 mA, 0 to 10V, 0 to 40 mV, potentiometer 0 to 6/160 kΩ **Sampling Time:** 4,1 ms (242 Hz frequency) **1 Digital Input:** Up to 4 setpoint selections, hold, run, tuning launch, start/stop cycle **Outputs: 2 Relays:** 5 A to 250 Vac (resistive) **DC Pulse:** 12 Vdc, 30 Ma **Analog:** Programmable for 4 to 20 mA, 0 to 10 Vdc, control or retransmission PV/SP **Serial Communication:** RS485 MoDBUS[®] RTU **Control Algorithms:** on/off with hysteresis, P, PI, PID, PD, time proportional **Tuning:** Manual or autotune **Data Protection:** Lock command/ alarm setpoint, access to parameters by password **Alarm Modes:** Absolute/threshold, band, high/low deviation; loop break alarm function **Soft-Start:** Rising gradient expressed as °C or °F/hour **Programmer Function:** Start/stop, 3 steps pre-programmed cycle **CN245-R1-R2-F3-C4 with CN-CONFIG-MODULE shown smaller than actual size.** ## **Input Table** |**Input Type**|**Input Type**|**Range**| |---|---|---| |||-260 to 1360°C(-436 to 2480°F)| |||-40 to 1760°C(-40 to 3200°F)| |||-200 to 1200°C(-328 to 2192°F)| |Pt100ΩRTD||-200 to 600°C(-328 to 1112°F)| |Ni 100ΩRTD||-60 to 180°C(-76 to 356°F)| |Pt 500ΩRTD||-100 to 600°C(-148 to 1112°F)| |Pt 1000ΩRTD||-100 to 600°C(-148 to 1112°F)| |NTC 10 KΩThermistor||-40 to 125°C(-40 to 257°F)| |NTC 2252ΩThermistor||-40 to 150°C(-40 to 302°F)| |PTC 1 KΩThermistor||-50 to 150°C(-50 to 302°F)| |0 to 10 Volt||-999 to 9999| |0 to 20 mA||-999 to 9999| |4 to 20 mA||-999 to 9999| |0 to 40 mV||-999 to 9999| |Potentiometer||Maximum 6 KΩ| |Potentiometer||Maximum 150 KΩ| |**To Order**|**To Order**| |---|---| |**Model No.**|**Description**| |**CN245-R1-R2-F3-C4**|DIN rail controller, relay/relay/dc pulse or analog output (selectable for output 3),
