Technology has launched a new range of modular DIN-rail mounted CAN I/O expansion
modules that feature switchable TrioCAN I/O and CANopen DS401 protocols to
allow use across its Motion Coordinator motion and machine control families.
The range includes
separate and combined 16-point digital input and output modules, an 8-input +
4-output analogue module, and an 8-channel relay output module - all with
standard industrial signal levels and fully certified EMC emission and immunity
ratings. The new modules may be freely mixed to a maximum of 32 CAN addresses
for the P317, P318, P319 and P327 all at 500kHz in Trio Mode or up to 1MHz in
CANopen Mode. This allows generous and flexible I/O expansion capability with
considerably reduced machine wiring for OEMs and systems integrators using Trio
motion controllers or CANopen device users requiring standalone digital or
analogue system expansion for signal processing, actuators, feedback signal and
Supplied in compact
ABS enclosures, each measures 26 x 85 x 130 mm, the new range is designed for
efficient panel installation and convenient monitoring with all modules featuring
individual channel status LEDs and removable front and top mounted screw
terminal blocks for power supply and I/O interfacing. For straightforward set
up, module address and CAN protocol selection is via front panel DIP switches located
behind a small window with a card slot which is aligned with the status LEDs
and may be marked as a visual channel reference. The range of CAN modules have been EMC tested
against and passed the EN 61000-6-2: 2005 for industrial noise immunity and
EN61000-6-4 : 2007 for industrial noise emissions.
When used with Trio's flagship MC464
Motion Coordinator and across the full Trio Motion Coordinator range where a TrioCAN
I/O communication card is fitted, the Motion Perfect 2 programming environment
automatically configures all I/O channels over the complete CAN bus with plug
and play simplicity. The integrated
controller I/O and external CAN I/O is seamlessly programmed with a choice of Trio's
TrioBASIC programming language, or G-code, or with IEC61131-3 on the advanced MC464
Motion Coordinator motion and machine control system. For those wishing to use
the CANopen DS401 protocol, Trio provides comprehensive documentation and technical
support to ensure trouble-free system integration.
The P319 is a combined
16 channel digital I/O module that replaces Trio's previous
P316 CAN expansion module with a functionally identical I/O rating that allows
drop in product replacement but in a much smaller footprint design. The 16
bidirectional I/O points are rated at 16 to 24V with 2500V isolation and output
capacity at 250 mA per channel with full overcurrent and temperature
protection. Power requirements are 24V at 1.5 W.
The P318 CAN 16
Input Module and P317 CAN 16 Output Module share identical specifications to
the bidirectional module but offer 16 full input or output points. Up to 256
digital I/O points may be configured on the bus for digital modules.
Trio's P326 CAN
Analogue I/O module combines eight +/- 10V inputs and four +/- 10V outputs, both having 1 kV isolation from the CAN bus. The
12-bit resolution will allow use in the vast majority of analogue I/O control
applications and up to four modules in Trio Mode (32 input channels and 16 output channels) and
32 in CANopen Mode(256 input channels and 128 output channels) may be
configured over a distance of up to 100 m in each CAN network.
The new P327 CAN
Relay Module provides eight outputs configured as four switch over contacts and
four normally open contacts rated for 0.5 A at 125V ac and 1 A at 24V dc. Up to
16 modules in Trio Mode and 32 in CANopen Mode provide a maximum relay output
count of up to 256 channels.
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
