THE Eurotherm 2216e DIN rail mounting signal converter incorporates a universal input which allows for nine internally stored thermocouple types (J, K, T, L, N, R, S, B & P) and process inputs such as 4-20mA, 0-20mA, 1-5V or 0-10V dc while another 11 thermocouple are available as factory downloadable inputs.
The 2216e can be fitted with an analog retransmission module to provide a standard isolated 4-20mA or 0-10V process signal proportional to the input.
However, an optional DeviceNet communications card can also now be fitted to allow for direct integration onto any standard DeviceNet network. Thus the 2216 can provide signal isolation and scaling of field signals directly onto a DeviceNet platform.
Note also that the DeviceNet communications module is also retrofitable if DeviceNet is installed at a future time. Modbus and Profibus communications are also available on some models.
Where alarm outputs are required the 2216e can be also configured for up to three relay outputs. A digital input can also be fitted to provide external selection for auto/manual transfer, standby mode, second setpoint or alarm acknowledgement.
The 2200e as a controller allows for programmable control modes of PID, ON/OFF or motorised valve, with dual outputs of heating and cooling. Simple heat treatment profiles can be programmed using the internal ramp generator and dwell timer.
With Eurotherm's PD/CTX advanced load-monitoring facilities, heater current may also be displayed, as well as open or short circuit faults detected. Common remote setpoint transfer between controllers is also available.
Advanced PID algorithms to provide stable 'straight line' temperature control. Self-tuning is included to optimise the control performance without the need for specialist knowledge or training.
Dual 4-digit displays provide the operator interface, the functionality of which can be customised to present only those parameters that an operator needs to see and adjust, while all other parameters are locked under password protection.
Configuration is achieved either via the front-panel interface or by using Eurotherm's "iTools" configuration package running under the Windows 95 or NT operating systems. Eurotherm Australia 02 9634 8444.
