1- or 2-Channel Circular Recorders CT5100 Series Circular Chart Recorders measure and display up to two process variables. Choose from a variety of programmable inputs. All recorder and alarm functions are easily configured via front 3-key pad with self prompting displays. Total panel depth of only 64 mm is required with only a 33 mm protrusion from the front of the panel. 250 mm Chart 1- or 2-Pen Versions, Thermocouple, RTD, dc Current, or Voltage Input Programmable Inputs 4-Digit 14 mm Display Specifications Inputs Input Types/Range: Thermocouple: J, K, T, R, S RTD: 100 Ù Platinum, .00385 Ù/Ù/°C Current dc: 0 to 20 mA, 4 to 20 mA. Internal 4.7 ohm Shunt Resistor Voltage dc: 0 to 25 mV, 0 to 50 mV, 10 to 50 mV, 0 to 5 V, 1 to 5 V Impedance: >100 MÙ for TC and mV inputs. 100 KÙ for 5 V inputs. 4.7 Ù for mA inputs RTD Excitation Current: 150 microamps, typical Input Scan Rate: 1 scan per second for non-RTD inputs; 1 scan per 1.2 seconds for RTD inputs Input Correction: Offset adjustment -999 to 999 units Sensor Fault Detection: Display goes to “SnSr” and pen goes upscale if a sensor break is detected. No sensor break can be detected for zero-based Volt and Milliamp ranges. Display goes to “Hi” 10% above span; display goes to “Lo” 10% below span or zero, whichever is higher Input Performance Under Reference Condition: Measurement Error: Type J, K, T, R, S and RTD: ±0.25% of span ±1 degree mA, mV and Vdc: ±0.25% of scaled span plus 1 least significant digit Cold Junction Compensation Error: ±0.2°C @ 25°C (±.36°F @ 75°F) Cold Junction Compensation Rejection: 0.04°/°C deviation from 25°C (0.07°/°F from 75°F) Linearisation Error: TC’s: ±0.25°C (.45°F) typical, ±0.5°C (10.9°F) worst case RTD’s: ±0.1°C (0.18°F) typical, ±0.3°C (0.54°F) worst case Ambient Temperature Error: ±0.01% of span per °C (1.8°F) deviation from 25°C (75°F) Common Mode Rejection: >120 db @ 50/60 Hz, 260 Vac max. Normal Mode Rejection: 85 db minimum @ 60 Hz or greater Isolation: 350 Vac, 500 Vdc. Inputs share a common signal ground Reference Conditions Ambient Temperature: 25°C (75°F) Relative Humidity: 60 to 70% Source Resistance: <10 Ù for TC input Lead Resistance: <0.1 ohm/lead balanced (Pt100) Recording Pen Type: Disposable fibre tip Pen Colour: Pen 1-red; Pen 2 -green Chart Size: 254 mm (10 in) diameter Chart Drive: Stepper motor Chart Rotation: User configurable: 8 hours, 12 hours, 24 hours, 48 hours or 7 days Chart Span: Bottom and top of span, -9999 to 9999 units Recording Performance Chart Recording Accuracy: 0.5% of chart span reference accuracy Chart Rotation Accuracy: ±0.5% of rotation time, assuming all backlash removed Operator Interface Display: Four-digit, 14 mm (0.56") high, red, seven-segment, LED display Status Indicators: Five red LED alarm status indicators, one green LED pen 2 indicator OOC CC O C RE SM arranty Programme Model CT5100-CE £555 Basic Unit R-57 www.omega.co.uk +44 (0)161 777 6611

Keypad: Three keys for programming and unit operation Display Modes: Normal: Process value(s) or blank Alarms Number: Up to two process alarms for each of two inputs Type: Process high or low Limit Device: Optional high/low limits for each input with latching output. Normally open output latches open. Red reset button included to the right of the display Hysteresis: Fully adjustable, 0 to 200 units, single sided Security: Alarm setpoint changes can be prohibited Sensor Fault Action: Alarm works normally in “Hi” and “Lo” conditions. Alarm relays are de-energised in a “SnSr” sensor break condition...
