SNAP-B12MC

Production Specification

NOTE: This rack is not suitable for SNAP PAC brains and rack-mounted controllers; see the SNAP-PAC-RCK12.

The SNAP-B12MC rack mounts a compatible SNAP brain (such as the serial B3000 or the SNAP-UP1-ADS) and 12 SNAP I/O modules. Analog, digital, and serial modules can be mixed on the same rack. Four-channel digital modules can be placed in the first eight positions only; 32-channel digital modules can be placed in any position. Field devices are wired to top-mounted removable connectors on the SNAP I/O modules. This rack also provides a screw-type terminal strip for field wiring common connections such as loop power distribution.

1 “Mixed” means the rack can hold analog, digital, and serial modules. Most Ethernet-based I/O processors handle all these types of modules; other processors do not. See the processor’s data sheet for details.

2 Power requirements shown are for a rack, a processor, and a full load of 2-channel analog modules (for the SNAP-D64RS, a full load of 4-channel digital modules). Power requirements for other SNAP modules are higher. See module data sheets.

3 “I/O Processor” means a SNAP brain or on-the-rack controller.

4 Four-channel SNAP digital modules can be used in positions 0–7 only.

5 Manufacturer’s part number (not available through Opto 22).

 

SNAP Racks Assembly Instructions

This legacy document describes how to install a legacy rack extrusion and how to install or remove a circuit board. It includes a list of SNAP rack accessories.

SNAP I/O Racks Data Sheet

SNAP B-series mounting racks are designed to hold an intelligent SNAP I/O processor (either a SNAP brain or an on-the-rack controller) and several I/O modules.
This data sheet includes detailed information and specifications for SNAP B-series racks as well as the digital-only SNAP-D64RS rack. Rack fuses and DIN-rail adapters are also included in the data sheet.

B-series racks are used with serial and some Ethernet I/O processors. With Ethernet processors such as the SNAP-B3000-ENET, B-series racks hold analog, digital, and serial modules. With serial processors such as the serial B3000 brain, they hold analog and digital modules.

NOTE: For racks to use with SNAP PAC brains and rack-mounted controllers, or with SNAP-UP1-M64 and SNAP Simple brains, see form #1684, the SNAP PAC Racks Data Sheet.

Video: Verifying Voltage at the I-O Rack

Verifying the voltage level at the I/O rack is very important for equipment safety and point value accuracy. This is the proper technique for reading the voltage level at the rack.
