ioPAC 8020 Modular RTU Controller
Initial Setup
System Architecture
The ioPAC 8020 consists of a CPU module that supports Ethernet and up to 5 RM-xxxx-T I/O modules. The
brains of the system is the CPU Module, which collects information from each I/O module and manages their
operation. Communication between the ioPAC 8020 and RM-xxxx-T I/O modules occurs through a Modbus/RTU
communication bus. Modbus Addresses for each I/O channel are fixed by the ioPAC 8020.
The ioPAC 8020 uses 24 VDC power inputs. One power input is required, and a second one can be used as a
backup power input. The ioPAC 8020 provides 5 VDC power to all connected I/O modules. When the total
current consumption of the I/O modules exceeds 1.5A, you will need to insert an extra power module.
Installing the ioPAC on a DIN-Rail
The aluminum DIN-Rail attachment plate should already be fixed to the back panel of the ioPAC 8020 when you
take it out of the box. If you need to reattach the DIN-Rail attachment plate to the ioPAC 8020, be sure the
spring-loaded bracket is situated towards the bottom, as shown in the following figures.
NOTE
You can purchase a wall-mounting or rack-mounting kit separately. The ioPAC 8020 mounting kit is identical
to the one for the EDS-600.
STEP 1: If the spring-loaded bracket is locked in place, push the recessed
button to release it. Once released, you should feel some resistance from
the spring as you slide the bracket up and down a few millimeters in each
direction.
