Configure the system by selecting either two, four, or six input channels which accept any of the Signet sensors, and/or other manufacturer's sensors via a 4 to 20 mA signal converter. To complete your unit, choose a power module with universal AC line voltage or 12 to 24 VDC. Analog output and relay modules are easily installed. The 8900 will support up to four additional relays via an external relay module. To build a functional 8900 controller, choose the base unit (listed here), power module, and input/output (I/O) module. Find links to additional modules at the bottom of the page.
