MVAJ13D1GB0780A Tripping and Control Relays

The IOR810 is the gateway module that connects Symphony
Plus SD Series as well as HR Series controllers to S800 I/O.
The IOR810 provides an additional way to utilize S800 I/O as
part of a Symphony Plus or Symphony Harmony control system
with sequence of events (SOE) capability. The accuracy of SOE
time-stamping is determined by specification of each S800 SOE
digital input module type.
The IOR810 interfaces the HN800 I/O bus (electrical or fiber
optic) to the existing S800 I/O Modulebus (fiber optic only). The
core function of the IOR810 is to scan the S800 I/O modules
and provide this information to the Symphony Plus controller via
HN800. The IOR810 can connect to, and scan up to, seven S800
cluster modems via fiber optic Modulebus. Each cluster modem
can support up to twelve S800 I/O modules.

chain has a maximum distance of 15 meters if plastic fiber
cable is used, or 200 meters if HCS fiber cable is used, or
1000 meters if TB825 optical media converters and glass
fiber cable are used. Cluster modems can be either nonredundant or redundant.
The IOR810 receives its configuration information from the
Symphony Plus controller using standard Symphony Plus
function codes to specify the S800 I/O data. It will handle
inputs and outputs, analog and digital signal types, pulse
counters and sequence of events (SOE) data collection.
