to 16-bit resolution. The measurement range is defined by parameterization with an accuracy of 0.1% FSR with the exception of EP3124, which 0.25% FSR. The parameters for the measurement range can be individually set for each channel.

The EP-3704 module can detect up to 4 analog resistance temperature detectors. The resolution is 16 bit per channel.

The EP-3804 module can detect up to 4 analog thermocouple sensors or voltages between ± 15 mV and ± 2 V.

The wiring connectors on each module are color coded for ease of wiring. Refer to the section,

Each module features a type plate, which includes identification information, the key technical specifications, and a block diagram. In addition, a QR code allows for direct online access to the associated documentation. The software for reading the QR code must support inverted QR codes.

Markers are available as accessories for labelling equipment. Each I/O module can be labelled using the markers to ensure clear identification when replacing individual modules or electronic units.

A green Module Status LED indicates there is communication on the system bus. In addition, each channel has its own status LED.

Field Wiring for additional information.

The RSTi-EP station is usually installed on a horizontally positioned DIN rail. Installation on vertically positioned DIN rails is also possible.

Modules should to be allowed to de-energize for a minimum 10 seconds after power down, prior to starting any maintenance activity.

Refer to the RSTi-EP Slice I/O Module User Manual (GFK-2958) for additional information.

Refer to the RSTi-EP Power Supply Reference Guide, a software utility available on PME V9.00, for detailed power-feed requirements.

Module Features

 Spring style technology for ease of wiring  DIN rail mounted  Double-click installation for positive indication of correct installation  Up to 8 analog inputs  Supports indirect firmware update through network adapter using Web
