Data Sheets

WTX4 Isolated DAQ Module: Can be a mix of up to 32 digital input/outputs, 16 analog input/outputs, or 16 thermocouple inputs. Full electrical isolation from power supply and communications bus.
WTDIO-M Digital I/O Module: 14 I/O channels individually configured for input or output. Each channel uses standard TTL level signals, no protection. Automatic decoding of 4x4 matrix keypad.
WTDIN-M Digital Input Module: 8 wide range digital input channels with high voltage transient protection. 2 high current open collector outputs with automatic overload shutdown.
WTDOT-M Digital Output Module: 8 high current open collector outputs with automatic overload shutdown. 2 wide range digital input channels with high voltage transient protection.
WTSSR-M Solid State Relay Module: 5 opto-isolated relays can be wired directly to existing buttons and switches to allow software control of their operation. Or use to switch external solenoids and actuators.
WTSSR-HV HV Solid State Relay Module: This unit is similar to the WTSSR-M but with an extended power supply input voltage range.
DIO-SSR Relay Controller Module: Used as the host to the Solid State Relay Module. Switches wired to it's inputs will control the on/off states of the WTSSR relays via a remote data link.
