E10-Relay+ — tiny relay-output ladder-logic PLC with screw terminals

Classic PLC · E-series

E10-Relay+

The relay-output sibling of the E10-npn+: a tiny, low-cost ladder-logic PLC whose 0–250V AC relay outputs switch mains loads directly, replacing bulky relays and timers in a control panel. A built-in RS485 port lets up to 248 units network as remote I/O.

6 DI / 4 Relay DO 250V AC relays RS485 + Opto-232 Host-link protocol WinTRiLOGI
  • Relay outputs switch up to 250V AC loads directly
  • Replaces bulky relays, timers and counters at very low cost
  • Built-in RS485 — network up to 248 units over 1200 m
  • Programmed with free WinTRiLOGI v3.5 (ladder), simulator included

Overview

Relay outputs for mains-voltage loads.

The E10-Relay+ is the relay-output member of the enhanced E10+ family. Like the E10-npn+, its timers and counters support set values from 0–9999, program capacity is 216 steps, and it is programmed with WinTRiLOGI v3.5 under Windows.

Its 0–250V AC relay outputs switch mains-voltage loads directly, with no extra driver circuitry. A built-in RS485 port (with an Opto-232 adapter for RS232) provides host-link networking — the E10-Relay+ works standalone or as remote I/O for a host PC or master PLC, with up to 248 units on a twisted pair up to 1200 m (4000 ft).

Programming

Programmed with WinTRiLOGI — free, with a simulator.

The E10+ is programmed with WinTRiLOGI v3.5, a user-friendly Windows ladder-logic editor with a built-in offline simulator — write and fully test your program on a PC before connecting hardware. One PC can program a single unit over RS232 or up to 255 units over the RS485 network.
