Onboard I/Os¶
The AC500 CPU PM554 provides 8 Onboard Digital Inputs (24 V DC) and 6 Onboard Digital Outputs (depending on variant 24 V DC transistor outputs or relay outputs).
The AC500 CPU PM564 provides 6 Onboard Digital Inputs (24 V DC), 6 Onboard Digital Outputs (depending on variant 24 V DC transistor outputs or relay outputs), 2 Onboard Analog inputs (voltage 0 … 10 V) and 1 Onboard Analog Output (voltage 0 … 10 V or current 0 … 20 mA / 4 … 20 mA). The Onboard Analog Inputs can be configured as Digital Inputs, so 8 Onboard Digital Inputs may be available if no analog inputs are needed.
Numbers and types of the Onboard I/Os are listed in the table below:
| CPU type | Power supply | No. and type of digital inputs | No. and type of digital outputs | No. and type of analog inputs | No. and type of analog ouputs |
|---|---|---|---|---|---|
| PM554-T | 24 V DC | 8 x 24 V DC | 6 x 24 V DC, 0.5 A max. (transistor) | none | none |
| PM554-T-ETH | 24 V DC | 8 x 24 V DC | 6 x 24 V DC, 0.5 A max. (transistor) | none | none |
| PM554-R | 24 V DC | 8 x 24 V DC | 6 x relay output, 2 A max. | none | none |
| PM554-R-AC | 100 to 240 V AC | 8 x 24 V DC | 6 x relay output, 2 A max. | none | none |
| PM564-T | 24 V DC | 6 x 24 V DC* | 6 x 24 V DC, 0.5 A max. (transistor) | 2 x voltage * | 1 x voltage or current |
| PM564-T-ETH | 24 V DC | 6 x 24 V DC* | 6 x 24 V DC, 0.5 A max. (transistor) | 2 x voltage * | 1 x voltage or current |
| PM564-R | 24 V DC | 6 x 24 V DC* | 6 x relay output, 2 A max. | 2 x voltage * | 1 x voltage or current |
| PM564-R-ETH | 24 V DC | 6 x 24 V DC* | 6 x relay output, 2 A max. | 2 x voltage * | 1 x voltage or current |
| PM564-R-AC | 100 to 240 V AC | 6 x 24 V DC* | 6 x relay output, 2 A max. | 2 x voltage * | 1 x voltage or current |
| PM564-R-ETH-AC | 100 to 240 V AC | 6 x 24 V DC* | 6 x relay output, 2 A max. | 2 x voltage * | 1 x voltage or current |
* PM564 has 2 analog inputs which can be configured as digital inputs. If the analog inputs are configured as digital inputs, 8 digital inputs totally are available.
Note
The 2 analog inputs are not electrically isolated from the 24 V power supply of the CPU.
All inputs (DI0 … DI7) and all outputs (DO0 … DO5) belong to 1 group. The inputs and outputs are group-wise electrically isolated.
