TC5042 Temperature Humidity Pressure Carbon Monoxide and Carbon Dioxide

Description

The TC5042 is a pre-programmed stand alone controller for temperature, humidity, pressure, flow, CO & CO2. It is the new ET45 and is designed to be a replacement / upgrade for the ET45 and TC2000 range. It will also replace the XC2542 controller for many applications.

The TC5042 has currently 30 pre-programmed function blocks. It is only necessary to scroll through the functions and select one. The controller is then programmed. The default program block is 2 Heat, 2 Cool. Any parameter of the program can also be changed, eg: proportional bands, differentials, PWM rates, PI & PID functions, etc.

The controller is housed in a 4 DIN module 70 x 88 x 62 mm enclosure. It comes with its own DIN rail mount or can be mounted on a standard DIN mounting rail. The TC5042 controller has a 2 x 16 character LCD display with white backlighting, 4 x blue relay status LED’s and 3 pushbuttons for INCREASE, DECREASE & SELECT.

The controller will operate with 1K, 2K and 10K NTC thermistor sensors and existing Regulator setpoints. It will also operate with PTC 1K Nickel and 1K Platinum sensors. The default is the 10K thermistor sensor. Up to 4 Smart Sensors can be connected to the controller.

The controller will accept 2 or 3 wire 4 - 20 mA inputs for Temperature, Humidity, Pressure, Flow, CO and CO2. The temperature input can also be a high temperature range such as 0 – 500C.

There are 3 analogue outputs plus one diode protected output of AO3. The analogue outputs are short circuit proof for low voltages. They will even protect against 24vac connected to them. The output will open circuit under fault conditions and will reset when the fault is removed.

There are 4 relay outputs, Relay 1 is a SPCO contact and Relays 2, 3 & 4 are SPNO contacts. The relays are rated at 5A 250VAC.

LCD Display

This is a 2 x 16 character LCD display with white backlighting. The top line will display the Temperature / Humidity / Pressure / Flow / CO or CO2. This line will remain permanently displayed in normal mode. The second line displays the setpoint. This can be adjusted by pressing the Select Button and using the Raise / Lower buttons to change the setpoint. Temperature is adjustable in 0.5 C increments. A third line displays the three analogue outputs.

Smart Sensors

The new range of Smart Sensors TR3800 will operate from the new controller. Power and Comms are supplied over a 2 wire non-polarised connection. Up to four smart sensors can be connected to the controller. The controller will recognise how many are connected and will average the sensors. One of the sensors can be a display type TR3840.

Configuration Menu

The TC5042 Controller can be configured for many different modes of operation. The standard programs are listed in the table below. To select a program, hold the Select button for ten seconds. Using the Increase / Decrease buttons, step through to the program you require. Press the Select button and the Controller is now programmed. The standard programmes can be altered for different applications. Refer to the TC5042 Instruction Manual for guidance in changing parameters.
