Opto 22s Four-Port Serial I/O Module

Part of the groov® EPIC system, the GRV-CSERI-4 mounts on any groov EPIC® chassis alongside a GRV-EPIC-PR1 processor and analog and discrete groov IO modules, to provide the mix of signals for any location.

The GRV-CSERI-4 from Opto 22 is a groov serial I/O module. It plugs into a groov EPIC® chassis alongside Opto 22’s new groov Edge Programmable Industrial Controller (EPIC) and discrete and analog input/output (I/O) modules, to provide the mix of analog, discrete, and serial signals needed at any location.I/O module

Many industrial automation applications require communication between the controller and multiple serial devices. This new module provides four independent and isolated serial ports for this purpose, communicating with RS-232 or RS-485 serial devices. Up to four modules can be installed in one groov EPIC chassis, providing a total of 16 serial ports to support these communication requirements. Each port is selectable for RS-232 or RS-485 mode, with programmable termination and bias as well as half- or full-duplex options in RS-485 mode. Baud rates of up to 1 Mbps are supported.

For serial devices communicating via standard protocols, the included PAC Control flowchart-based programming software offers communication handles to serial devices. Or use groov EPIC’s Ignition Edge® from Inductive Automation®, which provides support for hundreds of communication drivers. For serial devices requiring the development of custom drivers, groov EPIC supports secure shell access, SDKs, and a cross-compiler for custom user-written applications.

Once communication is established with serial devices, multiple programming options are available with groov EPIC to link devices. PAC Control provides English-language commands, and the included Node-RED, a flow-based development environment and runtime for edge data processing, handling, and communications, offers serial nodes users can download.

The rugged I/O module operates in temperatures from -40°F to 85°F and relative humidity (non-condensing) of 5% to 95%. Agency approvals include UL/cUL (Class 1 Div. 2); CE, ATEX (Category 3, Zone 2), and RoHS; DFARS; and CB Scheme.

The GRV-CSERI-4 plugs into a groov EPIC IO chassis. It pivots into a slot on the chassis and is held securely in place by a captive retention screw. Wiring is simplified with a top-mounted connector and spring-clamp terminals for easy connection to all types of RS-232 and RS-485 devices. The connector is held in place by a single, captive retention screw—but can be removed with field wiring intact for wiring in advance or easier module field replacement.

A swinging, two-position cover protects wiring from inadvertent contact, as does the dead-front design. The two positions of the cover offer the option of more space to accommodate wire sizes from 28 AWG to 14 AWG. The I/O module cover provides a touch-sensitive pad; simply touch the pad and the groov EPIC processor displays information about the module, including specifications and wiring diagrams. The module cover also provides a large LED to indicate module health at a glance, plus a transmit and receive LED on each port.

The GRV-CSERI-4 modules are hot swappable—which means they can be installed or removed without turning off the unit or stopping control—and self-identifying; as soon as you mount the module on the chassis, it communicates to the processor and identifies itself.

Each I/O module is factory tested twice before shipment and is guaranteed for 30 months.
