Ri/O Head/Receiver; Ri/O Head Installation (685E/785E/785Di785K Only); Procedure Setup & Install. Of S908 Ri/Op In Prim. Housing - Black & Decker d984 Installation Manual

RI/O Head/Receiver
The 381 E/385E/385D PLC' s only support local I/O not RI/O. Therefore the follow-
ing sections do not apply to these PLC' s. The RI/O head installation section ap-
plies to 685El785El785Dl785K PLC' s because these systems require an addition-
al hardware module that functions as the RI/O head (S908) and because
480E/485E/485K PLC' s have their RI/O head built-in. The RI/O receiver installa-
tion section applies to 480E/485E/485K and 685El785El785Dl785K PLC' s.
RI/O Head Installation (685E/785E/785D/785K ONLY)
The RI/O Interface has an exec cartridge for the remote I/O interface. Depending
on which cartridge has been installed, the RI/O drop limit is either 16 or 31. Your
RI/O exec cartridge installation is accomplished through an access panel in the left
side of the RI/O head (S908) module' s chassis.
