GE provides a range of RSTi-EP digital input modules with 4, 8 or 16 inputs,
Digital Input Modules
EP-1214, EP-1218, EP-1318, EP-125F, EP-1804
Digital Input Module with Time Stamp EP-12F4
which are primarily used to receive binary control signals from sensors,
transmitters, switches or proximity switches. Their flexible design allows them
to meet your demands with reserve potential.
All modules are fully compliant with IEC 61131-2. They can be switched on the
input side with type-1 and type-3 sensors in accordance with IEC 61131-2.
The wiring connectors on each module are color coded for ease of wiring.
Refer to the section, Field Wiring for additional information.
The time stamp module EP-12F4 can detect up to 4 binary control signals and
provide them with a time stamp (resolution 1 μs). Depending on the
configuration of the module, up to 5 or 15 time stamp entries can be
evaluated.
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. Additionally, there are Yellow LEDs for each input to indicate when it is
active. Refer to the section,
LEDs 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.

RSTi-EP Slice I/O Digital Input Module with Time Stamp
Field Wiring
The connection frame can take up to four connectors, and four wires can be connected to each connector. The Spring
style technology allows for either finely stranded or solid wire with crimped wire-end ferrules or ultrasonically welded
wires, each with a maximum cross-section of 1.5 mm² (16 guage), to be inserted easily through the opening in the
clamping terminal without having to use tools. To insert fine stranded wires without wire-end ferrules, the pusher must
be pressed in with a screwdriver and released to latch the wire.
Connector Block with Four Wire Connectors
Note: Image is for illustration of color coding only.
Connector Specifications:
• conductor cross-section 0.14 to 1.5 mm² (26 – 16 guage)
• max. ampacity: 10 A
• 4-pole
The pushers are color-coded for the following connections:
• White Signal
• Blue GND
• Red 24 V DC
• Green Functional earth (FE)
The modules do not have a fused sensor/activator power supply. All cables to the connected sensors/actuators must be
fused corresponding to their conductor cross-sections (as per Standard DIN EN 60204-1, section 12).
Refer to the RSTi-EP Slice I/O Module User Manual (GFK-2958) for additional information.
