INTRODUCTION

This manual describes the operation and use of the C&H Model M222 4 Channel Form C Power
Relay M-Module (Part Number 11029570). This module was formerly manufactured by HP
(Agilent) as Model E 2274A. C&H obtained the manufacturing rights from Agilent and now
manufacturers it as C&H Model M222. This mezzanine module is designed to interface within
any M/MA-Module carrier adhering t o the ANSI/VITA 12-1996 M-Module specification. These
carriers are available in man y formats such as Ethernet, VME, VXI, PXI, cPCI, and the PC.

Contained within this manual are the physical and electrical specifications, installation and startup
procedures, functional descriptio n, and configuration and pro gramming guidelines to adequately
use the product.

This manual is based on a low level register access, and is written in such a manner t o provide
understandi ng to the user based on this type of access. If a driver is provided, please refer to the
driver documentation for instruction using the higher leve l interface provided by the driver.

1.0 GENERAL DESCRIPTION

The M222 provides 4 individual Form C (SPDT) channels for general purpose switching and
control of external devices on a single wide M-Module adhering to the ANSI/VITA 12-1996
specifi cation for M-Modules. With its 5 ADC per channel current rating, it can be used to switch
external power supplies. The module may be installed on any carrier board supporting the M­Module specifi cation. Carriers are available that allow the module to be used in Ethernet (LXI),
VXI, VME, PCI, cPCI, PXI and other system architectures.

1.1 PURPOSE OF EQUIPMENT

The M222 can connect multiple instruments to multiple points in your test system. This provides
flexible interconnection between test points, instrumentation, factory automation, and test
fixtures.

CAUTION: This module DOES NOT have provisions for on-board current

limiting components (if input current can exceed 5A DC or 5A
AC, you must install external current limiting circuitry)

1.2 SPECIFICATIONS OF EQUIPMENT

1.2.1 Key Features

 Four (4) Individual Form C (SPDT) Power Relays
 Non-latching Relays
 Single-wide M module provides high density and maximum flexibility of configuration

1.2.2 Specifications

The M222 incorporates the standard 40-pin, 20x2 row connector interfaces to the carrier board
for power and data/control, but does not have the 24-pin optional connector for carrying user­connections back onto the carrier board.

The user input/output is provided through a standard 44-pin D-subm iniature female receptacle. A
mating connector kit can be ordered separately as AM111 (C&H Part Number 11029700-0001).
CONEC part number 302A10889X (or equivalent) is used on the assembly. The connector pin­outs are shown in Appendix A.
