The Ronan Series X87 features continuous monitoring of temperature, vibration or almost any other process variable. The system consists of single or multiple chassis, a master module, and the required number of input modules. The master module provides digital readout of the input variables as well as each of the setpoints. The Master module also provides push buttons to test, acknowledge, and reset alarm indications. The input signals from each sensor are conditioned and scaled in the input module and continuously compared against the user adjusted setpoints. Input modules can also retransmit any portion of the measurable input range in an isolated voltage or current format. Optionally, the input and setpoint values can also be downloaded to a DCS, PLC, or plant computer via a simple RS232 interface system. The X87 complies with API 670, and is ideal for control room or field mounting in NEMA enclosures.
