DIN rail isolator, alarm, controller.
THE Eurotherm 2216e precision controller is now available with a DIN rail mounting base. The modular construction and availability of a range of I/O cards allows this one module to be configured for a number of applications such as isolated signal conversion and alarming, indication and PID loop control.
The 2216e is also all compatible with industry standard serial communication protocols - DeviceNet and Modbus, allowing for easy connection to supervisory control and data logging systems.
A universal input allows for nine internally stored thermocouple types (J, K, T, L, N, R, S, B & P) plus millivolt 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.
An optional isolated dc output card allows the 2216e to be used as a signal isolator with software selectable outputs.
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.
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.
The simple-to-use 2216e provides an ideal process control - isolation - alarm - indication solution many applications. Eurotherm Australia 02 9634 8444.
