Combined Module
These SIMATIC S7-200 expansion modules incorporate equal numbers of both digital inputs and outputs, and are available with either transistor or relay outputs.
Note
Expansion modules cannot be used with S7-221.
S7-200 Expansion Modules for 2nd & 3rd Generation
A range of digital and analogue expansion modules to increase the I/O capacity of the S7-200 CPUs. A maximum of 2 modules can be used with S7-222, with a maximum of 78 I/O, up to 7 modules may be used with S7-224 and S7-226 CPUs, with a maximum of 128 I/O 248 respectively. The modules are available in 24Vdc or 85-245Vac powered versions, and include digital input, output and combined forms, plus analogue input, output and temperature sensor modules.
In addition to digital signals the S7-200 series can process analogue signals from sensors or actuators directly by using an analogue expansion module.
