ScanMeg Inc. Module SIM‐P

Introduction

The use of a SIM‐P module changes a simple type P photocell that has a detection feature into a
complete scanner with different outputs, and also maintains all the features of a photocell. It is like
getting a sophisticated photocell and a high‐tech scanner at the same time.
The type P sensor head is an area photocell made up of an emitter and receiver. The sensor detects
objects as small as 0.1 inch (2.5mm). The emitter and the receiver can be mounted up to 100 feet
(30m) apart. The SIM‐P module has multiple outputs: a PNP contact, a NPN contact, an RS‐232 serial
communication port, an RS‐422 serial communication port and two analog 4‐20mA outputs.
Dimension of the object present in the field of view and its position are available through the analog
and the serial link outputs. The NPN and PNP outputs are used for the presence of an object. The
module also has a membrane keypad, a 32 alphanumeric display (2x16) and LED to show different
status.
The head is a closed enclosure with a military, quick‐disconnect connector. The rail‐mount SIM‐P
module is supplied with the emitter and receiver. All parameters can be directly programmed with
the Sensor Interface Module for Photocell. The emitter and the receiver are directly connected to the
SIM‐P.
A 32‐character, alphanumeric digital display shows each parameter and available configuration. The
SIM‐P is configured using an 8‐key membrane. Status of each cell of the receiver (blocked, cancelled;
not blocked) can be seen on the receiver head through its window, or on the SIM‐P remote display.
Connection of the emitter and receiver is simple using four colored wires and each color is identified
directly on the terminal's connector located on the SIM‐P. Two terminals are present, one for the
receiver and one for the emitter. These connectors are not dedicated as they can either accept
emitter or receiver. The only restriction is to have an emitter unit and a receiver unit with the same
length connected to the SIM‐P.
Mechanical, electrical or interconnection drawings are available in AutoCAD format. If required please
