Description
Product Name: 700-K31Z-ZJM Allen Braley Input module
Product details:
The 700-K31Z-ZJM is a specific configuration of the Allen-Bradley 700-K MCS Miniature Control Relay.
-
Product Type: Miniature Control Relay (Industrial Control Relay)
-
Series: 700-K (Miniature)
-
Terminal Type: Screw-type terminals, designed for secure and reliable wiring connections.
-
Control Voltage Designation: ZJM indicates the coil voltage and system control voltage range. This is typically a 24V DC system control voltage, with an operating range of 17V to 30V DC.
-
Contact Configuration: 31 indicates the number and type of auxiliary contacts. Specifically, it has 3 Normally Open (N.O.) contacts and 1 Normally Closed (N.C.) contact.
⚙️ Product Parameters (Specifications)
| Feature | Specification |
| Coil Voltage (System Control Voltage) | 24V DC (Typically operating range 17V to 30V DC) |
| Contact Configuration | 3 N.O. (Normally Open) and 1 N.C. (Normally Closed) |
| Terminal Type | Screw Terminals |
| Mounting | DIN Rail or Panel Mount |
| Current Rating | Typically rated for small to medium control loads, often up to 10 A (depending on the load type). |
| Size | Miniature/Compact (IEC Standard) |
| Wire Size | Compatible with specific wire sizes for control wiring (e.g., 22–14 AWG) |
✅ Product Advantages (Benefits)
The 700-K series, including the 700-K31Z-ZJM, offers several benefits for control systems:
-
Space-Saving Design: Its miniature size is a key advantage, allowing for high-density mounting in control cabinets where space is limited.
-
Reliable Switching: Designed for switching low-energy signals and control circuits with high reliability.
-
Easy Wiring: Screw-type terminals provide a robust and familiar method for installation and maintenance.
-
Global Standard: It is an IEC (International Electrotechnical Commission) standard product, ensuring compatibility with international requirements.
-
Versatile Contacts: The combination of N.O. and N.C. contacts (3 N.O. / 1 N.C.) offers flexibility for various logic, interlocking, and signaling applications.
-
DC Coil: The 24V DC coil is standard in modern industrial automation, compatible with most PLCs and I/O modules.
⚠️ Important Considerations (Notes)
When using the 700-K31Z-ZJM, keep the following in mind:
-
Load Type: While reliable for control circuits, this is a control relay, not a power contactor. It is not intended for switching high-power loads (e.g., large motors directly). Always check the contact rating against the load current and voltage.
-
Voltage Polarity: Since the coil is DC (24V DC), ensure correct wiring polarity to the A1 and A2 terminals for proper operation.
-
Over-Voltage Protection: While built to high standards, an external surge suppressor or diode may be necessary if the control circuit is highly sensitive or subject to significant inductive kickback from other devices.
-
Torque: When connecting wires to the screw terminals, always use the specified tightening torque to ensure a secure, low-resistance connection without damaging the terminals.
🛠️ Product Applications
The Allen-Bradley 700-K31Z-ZJM is a core component in many automated systems:
-
Interposing Relay: It’s frequently used to isolate sensitive PLC outputs from higher current/voltage loads, or to interface signals between different voltage levels.
-
Motor Starter Circuits: Used in the control logic for starting and stopping motor contactors, providing auxiliary contacts for holding circuits and feedback signaling.
-
Basic Logic and Interlocking: Implementing simple AND/OR/NOT logic functions in hardwired control circuits, and creating interlocks (e.g., preventing two motors from running at the same time).
-
Signal Repeater/Amplifier: Used to “repeat” a low-current signal to drive multiple indicators, alarms, or other relays simultaneously.
-
Small Machinery Control: Ideal for compact control panels in packaging machines, conveying systems, and assembly equipment.
