What is the purpose of interposing relay panel?
Interposing relay panel is an Instrument / Electrical cabinet used for hardwired signal (digital inputs and outputs) interfaces between Instrumentation and Control Equipments system and associated circuit breakers,or other electrical devices for monitoring, controlling
What is a interposing relay?
In general, a DCS or PLC, handles numerous discrete I/Os. One common I/O module (board) is used to supply 8, 16 or more points. Discrete output circuits from a DCS typically use low power level signals (transistors, micro relays) which cannot be sent directly to the field devices such as electromagnetic valves or motor control circuits. That is why interposing relays are often necessary. These relays play an important role by amplifying the current capacity of the contact signal of the I/O module allowing larger current flow. In addition, discrete input circuits normally can handle only dry contacts or wet contacts of low voltage, which also require interposing relays. For example, let's say the relay of a PLC can only accommodate 0.5A at 220 VAC, but the solenoid which is to be connected to the relay requires 1.2A at 220 VAC. In this case, an interposing relay with contacts rated for operation at 1.2A at 220 VAC would be used as an interposing relay "between" the PLC relay and the solenoid. The coil of the interposing relay should require less voltage and current than the driving relay is rated for, and the contacts of the interposing relay must be rated to handle the requirements of the load (solenoid, light, contactor, motor, etc.).

Where is the battery located on a John Deere 2555?
Find the starter and follow the heavy gauge wire from the starter. It will go to the starter relay or battery. If it goes to the relay then follow the heavy wire from the relay which will go to the battery.
