Sontay, the market leader in control peripheral products, has announced the release of its new I/O control module in July 2006, the IO-RMA, which incorporates state of the art digital electronics for maximum simplicity, efficiency and accuracy in set up, commissioning and performance.

The IO-RMA Adjustable Relay Module replaces the IO-VRM1. It accepts a 0-10Vdc signal and provides an SPDT relay output with adjustable ON/OFF switching thresholds. LED indication shows the relay status and the 0-10Vdc input is and buffered for output to other controls.The switching points can be locked after adjustment to prevent tampering.

Applications include adjustable direct ON/OFF control of heating or cooling loads from a 0-10Vdc source, such as a BMS controller output or a Sontay TT911/0-10/1 temperature sensor. Multistage control is easily achieved by feeding the buffered output into another IO-RMA.

The I/O Modules are part of Sontay's comprehensive control peripherals offering to the UK building services market. Sontay products are renowned for their accuracy, reliability and discrete appearance and are used by many of the market leaders in the worldwide building controls industry. Their products and control solutions help improve building management system performance, reduce energy and maintenance costs and increase occupant comfort levels.
