I/O : S-Series

S Series I/O Modules

S-Series I/O Modules

SoftPLC offers this low cost, distributed I/O product line, which we call the "S Series". The S-Series modules can be used with any controller or computer with ModbusTCP or Modbus RTU master capability. S-Series modules are the best value for reliable, industrial modular ModbusTCP or Modbus I/O.

All S-Series modules are industrially rated, provide lightning and surge protection, and are panel or DIN rail mountable.

The S-Series modules provide extremely cost-effective protection and conditioning for a wide range of industrial control signals and systems. These modules are ideal when you have only a few I/O points, or need to distribute a small number of I/O points in several locations and you don't want to incur the overhead/cabling cost of a fieldbus network (eg: Profibus or DeviceNet).

Applications include HVAC or building automation controls, data acquisition, security systems, energy management, test stands, process monitoring, sorting conveyors, utilities, and remote installations.

  • Overview

    S-Series I/O modules are a family of compact and networkable data acquisition and control modules, with a wide range of available analog and digital input/output signal types. All modules are designed for reliable operation in harsh environments and are equipped with isolation and failure protection, and high resistance against noise-interference.

    Most modules support both ModbusTCP via Ethernet and ModbusRTU serial via RS-485, the industry's most widely used bi-directional, balanced transmission line standard.

    All modules include these standard features:

    • Mounting Options - DIN-rail or panel/wall mount
    • Removable screw terminals for signal wires to replace module without re-wiring
    • Wide input power range (eg: 10-30VDC)
    • Low power consumption
    • LED's for ease in troubleshooting wiring and communication network
    • Lightning, Static, Over Current, Over Voltage Protection
    • Number of input channels configurable to improve frequency
    • Operating Temperature -20~85oC (-13~185oF)
  • Physical/Environmental Specifications
