PC1 and PC3 Programmable HVAC Controllers

PC1 Programmable Controllers

OEM Technology Solutions PC1 range of programmable controllers have been designed and manufactured to meet the most demanding control and monitoring applications particularly in the rail and associated transportation industries.The PC1 controllers are low profile and are housed in rugged enclosures.

Each comes with adequate mounting points and optional DIN mounting clips. All controllers are equipped with an Ethernet por t for connection to the Local Area Network. Control and monitoring data maybe passed between controllers or onto the management system.

The controllers have been designed to operate on a wide range of supply voltage and in demanding environmental conditions, making them ideal for rail and wider transpor t applications.

The I/O on each controller may be extended by connecting addition I/O Expansion Modules to the RS485 por t. I/O Expansion Modules are available in a range of configurations including analogue and digital inputs and outputs.

PC3 Programmable Controllers

OEM Technology Solutions PC3 series programmable controller is an innovative new product for rail and transportation market and is ideal for applications such as rail air conditioning systems.

The PC3 is extremely configurable; select the number and type of PC3 I/O from a wide range of modules. More details. Choose your configuration and create your own industrial single board controller. The PC3 has been designed specifically for high reliability applications such as in the rail industry. The controller has been designed to comply with the strict railway standard EN50155 for electronic equipment used on rolling stock.

The PC3 supports international programming standards IEC61131-3 .

maintenance software interface
