CAN 16 Input / OutputCAN Module

P319The Trio CAN16 Input/Output module offers a compact DIN rail mounted I/O expansion capability for all Trio Motion Coordinators. Up to 16 P319 modules may be connected to the CAN network which may be up to 100m long.

This provides 256 distributed bi-directional input/output channels at 24Vdc level. All input points are high level, (24V = ON) all outputs are short-circuit proof and the I/O is completely isolated from the CANbus.

P319 modules may be mixed on the same bus, with other types in the Trio CAN I/O range. The Trio CANbus I/O expansion can considerably reduce machine wiring.

Inputs 16 x 24 Volt Input channels with 2500V isolation
Outputs 16x 24 Volt sourcing (PNP) output channels
Configuration 2 x 8 bi-directional input/output channels

EU Declaration of Conformity  

Trio’s new CAN-16 IO module, the P319 is an ideal low cost replacement for the P316 CAN-16 IO module. 

Both modules provide 16 bit-directional 24V Input/Output channels and both run the long-standing Trio CAN IO protocol on CANbus which is supported by all Motion Coordinators with a CANbus port. 

The P319 also uses less space on the DIN rail than its older cousin, although it should be noted that the connector layout is different, so some changes to cable lengths may be required when installing the new IO module. 

Here is a summary of the 3 requirements for form, fit and function compatibility.
