The new[1] ⁄32 DIN CN9500,[1] ⁄16 DIN CN9300 single display,[1] ⁄16 DIN CN9400 and CN9600 dual display controllers follow the OMEGA tradition of innovative design. The new CN9600 offers powerful process control and programmer capabilities. Building on the success of the CN132 and CN9000A series, the new models include several new features, the most important being the option of a low cost serial communicating system with easy to use Windows based software. **==> picture [24 x 7] intentionally omitted <==** **----- Start of picture text -----**

The CN9-SW series software bridges the gap between the “stand alone” system and full SCADA of Fieldbus control networks by providing a facility for remote supervision of up to 128 instruments using MODBUS protocol. It requires only a modest investment and can be operated by anyone with a medium specification PC or laptop that can be run with Windows 95, 98 or Windows NT. **P-33** **CN9300, CN9400, CN9500 and CN9600 Specifications** **P** **The DC Pulse output is allocated to SP1 and wired to switch the load (heater) using an SSR** **The relay output is allocated to SP1 and wired to switch the load (heater) using a contactor** ## **Specifications** **Power:** 100 to 240 Vac, ±10%, 50 to 60 Hz, 4 VA; optional 12 or 24 Vac/Vdc, ±20%, 50 to 60 Hz, 4 VA polarity is not required; the controllers are fitted with an internal 250 mA time lag fuse **Display:** 4-digit LED, 10 mm (0.4"), high brightness green display **CN9400/CN9600 Dual Display:** **Lower Display:** 9 mm (0.35") orange LED output indicators-flashing **SP1:** Square green **SP2:** Round red **SP3:** 2[nd] round red (CN9600 only) **Display Range:** -199 to 9999 counts (hi-res mode -199.9 to 999.9) **Range:** Sensor limited 2000°C (3500°F); -99.9 to 999.9° in 0.1° resolution **Thermocouple Cold Junction Compensation Rejection:** 20:1 (0.05°/°C) typical **Thermocouple External Resistance:** 100 Ω maximum **Thermocouple:** 9 types **Standards:** IPTS/68/DIN43710 **RTD Input:** Pt100 2-wire (0.00385) **CN9600 Only:** 3-wire RTD input **mV Range:** **CN9300, CN9400, CN9500 Linear Process Inputs:** 0 to 50 mV (1 Ω shunt resistor supplied for mA inputs) **CN9600:** 0 to 50 mV ± 0.1% **Calibration Accuracy:** ±0.25% of full scale ±1°C **Sampling Frequency:** Input 10 Hz, CJC 2 seconds **Common Mode Rejection:** Negligible effect up to 140 dB, 240 V, 50 to 60 Hz **Temperature Coefficient:** 150 ppm/°C sensor maximum **Output Device Options: Relay:** Form A/SPST contacts 2 A/250 Vac, resistive **SSd (DC Pulse Driver, CN9600):** To switch a remote SSR 5 Vdc (+0/-15%) 15 mA non-isolated -6 Vdc @ 20 mA **Analog (CN9600):** Accuracy 0 to 1% full scale typical, 4 to 20 mA (500 Ω maximum), 0 to 5 Vdc 10 mA (500 Ω minimum), 0 to 10 Vdc 10 mA (1 kΩ minimum) **Operating Ambient Range:** 0 to 50°C (32 to 122°F) **Case Material:** Flame retardant polycarbonate **Weight: CN9300, CN9400:** 120 g (4.3 oz) **CN9500:** 110 g (3.9 oz) **CN9600:** 180 g (6.4 oz) **1 ⁄32 DIN Panel Cutout Size:** 45 x 22.2 mm (1.77 x 0.87") 9.5 mm (0.374") maximum panel thickness **1 ⁄16 DIN Panel Cutout Size:** 45 mm square (1.772"), 9.5 mm (0.374") maximum panel thickness **Maximum Recommended Wire Size:** 18 AWG **Inductive Loads:** To prolong relay contact life and suppress interference, it is a recommended engineering practice to use a snubber circuit, such as OMEGA’s CNQUENCHARC. _OMEGACARE[SM] extended warranty program is available for models shown on this page.
