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.
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.
