LSI-16 REAR PANEL
Option Slot
The option slot allows for additional modules if required by the system design. A typical option module in this slot may provide eight
additional general purpose logic inputs, plus eight general purpose logic outputs.
System Fault Relay Connection
This relay is activated when the LSI-16 is fully operational. It may be used for informing external devices about the LSI-16’s operating
conditions or sounding an alarm that indicates the LSI-16 is not functioning reliably.
RS232
This port may be used for RS232 communication with the LSI-16 under special circumstances. Future implementations may provide
enhanced features via this port.
24V DC Connector and LED
This is the primary (main) power supply input for the LSI-16 and as such must be fed from a suitable source of 24V DC capable of 15 watts
(625mA). The 24V DC supply has to be sourced separately. In typical installations, this supply will be provided from a power supply
compliant with local norms and required standards (typically battery-backed). The adjacent LED indicates the presence of power.
IP30 Compliance
The LSI-16 is designed for ingress protection to the IP30 standard. In order to maintain this compliance, any unused terminal connectors
on the back of the unit must be tted with the supplied terminal blocks.
