Industrial relay selection: type, load, contacts and socket

Choose the relay by the circuit it switches and the supply available to its coil. General-purpose plug-in, slim interface, PCB and force-guided relays serve different purposes. A high thermal or maximum switching value is not a universal load rating.

Industrial relay and application comparison
Relay type / model	Contact choice	Load / application check	Mounting / base
ZJ10F general-purpose relay	2CO / 3CO variants	Panel control: check the selected AC/DC coil and load rating; do not infer motor suitability from a resistive rating.	10F-2Z-C4 socket / 10F-3Z-C1 socket
ZJ18F miniature relay	2CO / 3CO / 4CO variants	Multiple control circuits: choose the pole count and verify the rating per contact.	18F-2Z-C11 socket · 18F bases
ZJ157F interface relay	1CO / 2CO variants	Relay interfacing: check coil power, actual switched voltage and current, and minimum load.	157F-1Z-C5 socket · 157F bases
ZJ41F slim interface relay	1CO	Dense control panels: check the signal/load rating and coil suppression option.	41F-1Z-C2 base / 41F-1Z-C6 base
ZJ115F PCB power relay	Choose the exact model and pole version	Board-mounted loads: compare current, temperature and endurance at the actual load.	Direct PCB solder terminals; no DIN-rail socket.
ZJ14F relay	Select the required 1CO / 2CO version	Board or interface design: confirm the terminal version and load specification.	14F PCB sockets; verify the selected footprint.
ZJA4 / ZJA6 force-guided relay	A4: 2NO+2NC or 3NO+1NC. A6: 5NO+1NC, 4NO+2NC or 3NO+3NC.	Components for a monitored safety design; not a ready-to-use safety controller.	A4 screw base / A4 push-in base · A6 screw base / A6 push-in base

Specify the load before choosing the current rating

Load information for relay selection
Load	What to provide	Why it matters
Resistive heater / test load	Operating voltage, steady current, duty and ambient temperature.	Use the applicable resistive rating and endurance data.
Solenoid / contactor coil	AC or DC, steady current, inrush and suppression circuit.	Inductive switching stress differs from resistive operation; coil suppression can affect release time.
Lamp / LED driver / power supply	Input type, inrush peak/duration and switching frequency.	A low steady current can coexist with a much higher turn-on current.
PLC / low-level signal	Minimum voltage/current, required isolation and switching life.	Check minimum load and contact material; a power-contact rating alone is insufficient.
Motor	Motor-specific rating, starting current and switching duty.	Do not convert a general-purpose resistive ampere rating into a motor rating.

See relay application precautions for the distinction between inductive and resistive switching. Model-specific JINHONG data remains the basis for selecting our products.
