CN1504-Series

Supported Applications

The Omega CN1500 Series is a compact 1/8 DIN multi-zone ramp and soak controller designed for process control applications requiring up to seven independent zones in a single enclosure. The series integrates features of multiple full PID controllers, allowing each zone to be independently programmed with its own ramp/soak profile, setpoint deviation display, and PID parameters (Rate, Reset, Proportional band). It supports automatic scanning and captures maximum and minimum readings for each monitored zone.

Operating Conditions & Performance

The CN1504-Series accepts a wide range of input signals including J, K, T, E, R, S, B thermocouples; 0.00385 and 0.00392 RTDs (2-wire); 400 Series thermistors; and linear inputs for current (4 to 20 mA), millivolt (0 to 100 mV), and voltage (0 to 10 V). Accuracy specifications vary by input type:

• Thermocouples J, K, T, E: ±1°C ±1 count (±2°F ±1 count)
• Thermocouples R, S, B: ±3°C ±1 count (±6°F ±1 count)
• RTD 0.00385 and 0.00392: ±1°C ±1 count (±2°F ±1 count)
• 400 Series Thermistor: ±0.5°C ±1 count (±1.0°F ±1 count)
• Linear Input (Current, Millivolt, Voltage): 0.05% FS ±1 count

Cold junction compensation error is specified as +/- 0.5 C for ambient temperatures between 10C to 45C. The unit features a display test that briefly indicates "8.8.8.8.8.8." on power up and provides an open thermocouple indication of 'HELP'.

Configuration Options

The series is available in two primary configurations: the CN1504 (4-zone controller) and the CN1507 (7-zone controller). Each zone supports programmable heating or cooling outputs with On/Off control or full PID control. Output signals include a 5 Vdc drive @ 50 mA open collector.

Power supply options are configurable via ordering suffixes:

• Standard: 120 Vac 50/60 Hz, ±10%
• Suffix -1: 240 Vac power
• Suffix -2: 12 Vdc @ 900 mA, ±20% (Note: Data sheet lists 15VDC in overview but specifies 12 Vdc in ordering table; the series supports both configurations as documented)

The controller utilizes Euro-style plug-in connectors for electrical connections. An optional accessory, CNQUENCHARC, provides a noise suppression RC snubber (2 leads) rated for 110 to 230 Vac.

Key Product Differences

Differences within the series are defined by zone count and input type selection. The model number guide follows the format CN1504(*) or CN1507(*), where the suffix indicates the primary input code:

• CN1504 / CN1507 TC: Supports J, K, T, E thermocouples, 4 to 20 mA, and 0 to 10 Vdc
• CN1504 / CN1507 RTD: Supports 100 Ω RTD, 4 to 20 mA, and 0 to 10 Vdc
• CN1504 / CN1507 TH: Supports Thermistor (400 Series), 4 to 20 mA, and 0 to 10 Vdc
• CN1504 / CN1507 R/S/B: Dedicated models for specific high-temperature thermocouples with linear input options
• CN1504 / CN1507 MV: Supports 100 mV, 4 to 20 mA, and 0 to 10 Vdc

The physical dimensions for the enclosure are 65 H x 117 W x 178 D mm (2.5 x 4.6 x 7") with a weight of 992 g (2 lb, 3 oz).
