Description
K3
Optional relay The function of this relay is customer-configured. It is possible to
implement functions like a follow-up relay for ventilator control, or to
bypass the fault relay at system startup. K3 can also be used as an
additional fault relay or limiting relay, by re-parameterization.
ANALOG AND DIGITAL I/O
There are four standard and two optional I/O connectors on the front of the unit:
• RS-232 (with power) connector, for the optional Thyro-Touch display
• μUSB connector, for configuration using the Thyro-Tool Pro PC software
• 9-pin digital I/O connector, with 6 digital inputs
• 9-pin analog I/O connector, with 3 analog inputs, and 3 analog outputs
• Optional 16-pin analog/digital I/O connector, with 4 digital inputs, 3 digital
outputs and 3 analog inputs
• Optional 16-pin digital I/O connector, with 9 digital inputs and 3 digital outputs
Up to two of the optional 16-pin I/O ports may be installed in the unit. Each I/O port
line can be reconfigured to serve any function, as needed for the application.
